14. A system for projecting an optical pattern of interest onto a modified retinal area of a human eye, the system comprising:
a carrying frame for being worn by a patient;
a camera for capturing an image;
a projector device for projecting a pulsed light beam reflecting a pattern of interest onto the modified retinal area of the human eye, the pulsed light beam derived from the image captured by the camera;
an alignment device for adjusting a position and an orientation of the projector device with respect to the carrying frame and with respect to an axis of the human eye; and
a processor device being in communication with the camera and the projector device, wherein the processor device is adapted for converting images captured by the camera into patterns of interest used as a basis for the pulsed light beam;
wherein the projector device and the camera are attached to the carrying frame,
wherein the camera and optics of the projector device are arranged facing opposite sides of the projector device such that the optics face toward the human eye and the camera faces away from the human eye and the camera and optics being arranged such that an axis of the camera and an axis of the optics are aligned lengthwise and concentric,
wherein the system is configured to operate such that the pulsed light beam is projected onto the modified retinal area of the human eye while keeping the axis of the camera and the axis of the optics aligned;
wherein the optics are configured for projecting the light beam from the exterior of a human eye at a pupil of the eye, and wherein the optics are configured such that an exit pupil diameter of the light beam is set smaller than an eye pupil diameter of the eye.
